OK, I put JD Fortune as lead of INXS, but I guess I should have put Michael Hutchence. I did abysmally on the rest. I think I only managed to get about 3 right!

Actually they are both correct, since JD Fortune became the lead singer after Hutchence's death. Looking at the wording of the actual question, I guess Hutchence was the one most known though, making him the correct answer. However, since that wasn't a group I listened to, I only know JD Fortune as the lead singer. And I missed it either way! LOL
